    6.
      ANTI-DILUTION
      PROVISIONS.

    


    (a)
      The
      number of shares of Common Stock and the Purchase Price per Warrant Share
      pursuant to this Warrant shall be subject to adjustment from time to time as
      provided for in this Section 6(a). Notwithstanding any provision contained
      herein, the aggregate Purchase Price for the total number of Warrant Shares
      issuable pursuant to this Warrant shall remain unchanged. In case the Company
      shall at any time change as a whole, by subdivision or combination in any manner
      or by the making of a stock dividend, the number of outstanding shares of Common
      Stock into a different number of shares, (i) the number of shares which the
      Holder of this Warrant shall have been entitled to purchase pursuant to this
      Warrant shall be increased or decreased in direct proportion to such increase
      or
      decrease of shares, as the case may be, and (ii) the Purchase Price per Warrant
      Share (but not the aggregate Purchase Price) in effect immediately prior to
      such
      change shall be increased or decreased in inverse proportion to such increase
      or
      decrease of shares, as the case may be.

     

    (b)
      In
      case of any capital reorganization or any reclassification of the capital stock
      of the Company or in case of the consolidation or merger of the Company with
      another corporation (or in the case of any sale, transfer, or other disposition
      to another corporation of all or substantially all the property, assets,
      business, and goodwill of the Company), the Holder of this Warrant shall
      thereafter be entitled to purchase the kind and amount of shares of capital
      stock which this Warrant entitled the Holder to purchase immediately prior
      to
      such capital reorganization, reclassification of capital stock, consolidation,
      merger, sale, transfer, or other disposition; and in any such case appropriate
      adjustments shall be made in the application of the provisions of this Section
      6
      with respect to rights and interests thereafter of the Holder of this Warrant
      to
      the end that the provisions of this Section 6 shall thereafter be applicable,
      as
      near as reasonably may be, in relation to any shares or other property
      thereafter purchasable upon the exercise of this Warrant.

    


    (c)
      Fractional
      Shares.
      No
      certificate for fractional shares shall be issued upon the exercise of this
      Warrant, but in lieu thereof the Company shall purchase any such fractional
      shares calculated to the nearest cent.

    


    (d)
      Rights
      of the Holder.
      The
      Holder of this Warrant shall not be entitled to any rights of a shareholder
      of
      the Company in respect of any Warrant Shares purchasable upon the exercise
      hereof until such Warrant Shares have been paid for in full and issued to it.
      As
      soon as practicable after such exercise, the Company shall deliver a certificate
      or certificates for the number of full shares of Common Stock issuable upon
      such
      exercise, to the person or persons entitled to receive the same.

    


    7.
      REPRESENTATIONS
      AND WARRANTIES.

     

    The
      Holder, by acceptance of this Warrant, represents and warrants to, and covenants
      and agrees with, the Company as follows:

    


    
      	 	
              (i)

            	
              The
                Warrant is being acquired for the Holder's own account for investment
                and
                not with a view toward resale or distribution of any part thereof,
                and the
                Holder has no present intention of selling, granting any participation
                in,
                or otherwise distributing the same.

            


    

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    
      	 	
              (ii)

            	
              The
                Holder is aware that the Warrant is not registered under the Act
                or any
                state securities or blue sky laws and, as a result, substantial
                restrictions exist with respect to the transferability of the Warrant
                and
                the Warrant Shares to be acquired upon exercise of the
                Warrant.

            


    

    


    
      	 	
              (iii)

            	
              The
                Holder is an accredited investor as defined in Rule 501(a) of Regulation
                D
                under the Act and is a sophisticated investor familiar with the type
                of
                risks inherent in the acquisition of securities such as the Warrant,
                and
                its financial position is such that it can afford to retain the Warrant
                and the Warrant Shares for an indefinite period of time without realizing
                any direct or indirect cash return on this
                investment.

                for its

                the Holder with at least forty-five (45) days prior written notice
                of such
                intention and, upon request from the Holder, will cause the underlying
                shares issuable under this Warrant designated by the Holder to be
                registered under the Act (such event, a "Piggyback
                Registration").

                reasonably request in order to facilitate the public sale or other
                disposition of the shares owned by

              Limitations.
                Notwithstanding the foregoing, if a Piggyback Registration is an
                underwritten offering and the managing underwriter advises the Company
                in
                writing that in its opinion the total amount of securities requested
                to be
                included in such registration exceeds the amount of securities which
                can
                be sold in such offering, the Company will include in such registration:
                (i) first, all securities the Company proposes to sell, and
                (ii) second, up to such amount of securities requested to be included
                in such registration by the Holders of the Company, which in the
                opinion
                of such managing underwriter can be
                sold.

      INDEMNIFICATION.

    


    
      	 	
              (a)

            	
              The
                Company may require, as a condition to including any Common Stock
                in any
                Piggyback Registration pursuant to Section 8 hereof that the Company
                shall have received an undertaking satisfactory to it from the Holder
                to
                indemnify and hold harmless the Company, each director of the Company,
                each officer of the Company who shall sign such registration statement,
                each person who participates as an underwriter (if such underwriter
                so
                requests) in the offering or sale of such securities and each other
                person, if any, who controls such underwriter within the meaning
                of
                Section 15 of the Act or Section 20 of the Exchange Act (each,
                an "Indemnified Person"), against any losses, claims, damages, liabilities
                or expenses, joint or several, to which such person may become subject
                under the Act or otherwise, insofar as such losses, claims, damages,
                liabilities or expenses (or actions or proceedings in respect thereof)
                arise out of or are based upon (i) any untrue statement or alleged
                untrue statement of any material fact contained in any registration
                statement under which such securities were registered under the Act,
                any
                preliminary prospectus, final prospectus or summary prospectus contained
                therein, or any amendment thereof or supplement thereto, or any document
                incorporated by reference therein, or (ii) any omission or alleged
                omission to state therein a material fact required to be stated therein
                or
                necessary to make the statements therein not misleading, if such
                actual or
                alleged statement or omission described in (i) or (ii) above was
                made in reliance upon and in conformity with written information
                furnished
                to the Company by such Holder for use in the preparation of such
                registration statement, preliminary prospectus, final prospectus,
                summary
                prospectus, amendment or supplement. Such indemnity shall remain
                in full
                force and effect regardless of any investigation made by or on behalf
                of
                the Company or any such director, officer, participating person or
                controlling person and shall survive the transfer of such securities
                by
                such Holder.

              (b)

            	
              The
                Company shall agree, in connection with any registration statement
                filed
                pursuant to Section 8 hereof, that the Company shall indemnify each
                Holder selling Common Stock pursuant to such registration statement
                and
                each other person, if any, who controls such Holder within the meaning
                of
                Section 15 of the Act or Section 20 of the Exchange Act, against
                any losses, claims, damages, liabilities or expenses, joint or several,
                to
                which such person may become subject under the Act or otherwise,
                insofar
                as such losses, claims, damages, liabilities or expenses (or actions
                or
                proceedings in respect thereof) arise out of or are based upon
                (i) any untrue statement or alleged untrue statement of any material
                fact contained in any registration statement under which such securities
                were registered under the Act, any preliminary prospectus, final
                prospectus or summary prospectus contained therein, or any amendment
                thereof or supplement thereto or any document incorporated by referenced
                therein, or (ii) any omission or alleged omission to state therein a
                material fact required to be stated therein or necessary to make
                the
                statements therein not misleading, provided that the Company shall
                not be
                liable in any such case to the extent that any such loss, claim,
                damage,
                liability or expense arises out of or is based upon an untrue statement
                or
                alleged untrue statement or omission or alleged omission made in
                reliance
                upon and in conformity with written information furnished to the
                Company
                by the Holder for use in preparation of such registration statement,
                preliminary prospectus, final prospectus, summary prospectus, amendment
                or
                supplement.

            


    

    


    
      	
            	(c)	
              If
                the indemnification provided for in Sections 10(a) or 10(b) above is
                unavailable to an indemnified party in respect of any losses, claims,
                damages or liabilities referred to therein, then each indemnifying
                party
                in lieu of indemnifying such indemnified party thereunder shall contribute
                to the amount paid or payable by such indemnified party as a result
                of
                such losses, claims, damages or liabilities, in such proportion as
                is
                appropriate to reflect the relative fault of the indemnifying party
                on the
                one hand and of the indemnified parties on the other in connection
                with
                the statements or omissions which resulted in such losses, claims,
                damages
                or liabilities, as well as any other relevant equitable considerations.
                The relative fault of the indemnifying party and of the indemnified
                parties shall be determined by reference to, among other things,
                whether
                the untrue or alleged untrue statement of a material fact or the
                omission
                to state a material fact relates to information supplied by the
                indemnifying party, or by the indemnified parties, and the parties'
                relative intent, knowledge, access to information and opportunity
                to
                correct or prevent such statement or
                omission.

            


    

    


    The
      Company and the Holder agree that it would not be just and equitable if
      contribution pursuant to this Section 10(c) were determined by pro rata
      allocation or by any other method of allocation which does not take into account
      the equitable considerations referred to in the immediately preceding paragraph.
      The amount paid or payable by an indemnified party as a result of the losses,
      claims, damages and liabilities or actions in respect thereof referred to in
      the
      immediately preceding paragraph shall be deemed to include, subject to the
      limitations set forth above, any legal or other expenses reasonably incurred
      by
      such indemnified party in connection with investigating or defending any such
      action or claim. No person guilty of fraudulent misrepresentation (within the
      meaning of Section 11(f) of the Securities Act) shall be entitled to
      contribution from any person who was not guilty of such fraudulent
      misrepresentation.
